Istanbul: Big Box is the all-in-one package for Istanbul, including the base game as well as both expansions, Mocha & Baksheesh and Letters & Seals. It also includes the Istanbul: Caravan Leader Mini Expansion, in the form of a small tile rather than a camel meeple.

This combination also gives players the option to play on a big 5 x 5 tiles bazaar.
